Description

LV 11047
TITLE
ANTISTATIC FINISH FOR DYEABLE SURFACTANT-CONTAINING POLY(M-PHENYLENE ISOPHTHALAMIDE) FIBERS
5 BACKGROUND OF THE INVENTION U.S. Patent 4,668,234 discloses the production of oriented, substantially amorphous poly(m-phenylene isophthalamide) fibers containing a surfactant in an amount sufficient to enable the fiber to be dyed a deep 10 shade. These fibers have very open structures which permit dyes to enter the fiber. Application of conventional antistatic finishes to such fibers leaves something to be desired since there is a loss of protection from electrostatic charging vith age. This 15 results in a deterioration of carding and draving performance in the conversion of staple fibers to yarns and fabrics. The loss of protection after a month or two of storage makes it difficult if not impossible to control inventories and shipping times to provide customers vith 20 fibers vhich process vithout undesirable stātie.
The present invention seeks to overeome the aforeraentioned deficiency to a signifieant degree.
Summarv of the Invention 25 The present invention provides a surfaetant- containing, substantially amorphous poly(m-phenylene isophthalamide) fiber of reduced stātie propensity having on its surface a two-component coating comprising from 65 to 90 % by veight of potasslum C^-C^ alkyl phosphate and 30 from 10 to 35 % by veight of a partially amidated polyalkyleneimine, said coating being present in an amount of at least about 0.2% based on the veight of the fiber.
Detailed Description of the Invention 35 The filaments to be treated in accordance vith the present invention are deseribed in U.S. 4,668,234. More particularly they are fibers of poly(m-phenylene isophthalamide) MPD-I vhich have been dried after 1 imbibition of from about 5 to 15% by weight of a surfactant as described in Example 1 part C, appearing at the top of column 8 of said patent.
To the dried MPD-I fibers described above is applied a coating of two active components. One of the components is a partially amidated polyalkyleneimine having a residual amine value of from about 200 to 800 as described in U.S. 3,597,265. It is formed by reacting a polyalkyleneimine having a molecular veight of 800 to about 5000 vith a fatty acid. In the Examples vhich follov, polyethyleneimine having an average molecular veight of about 1200 vas the polyalkyleneimine vhich vas partially amidated vith fatty acid as described in Examples 1-4 of said U.S. 3,597,265. The other active component of the antistatic finish of the invention is the potassium salt of an alkyl phosphate of vhich the alkyl group is 6 to 18 carbon atoms in length. Potassium n-octyl phosphate is preferred.
The tvo active components, namely, the partially amidated polyalkyleneimine and the phosphate salt can be applied to the fiber as an aqueous mixture or sequentially first the imine, then the phosphate (vith drying betveen applications).
The resulting coating should contain the components in the proportion of 65 to 90 veight percent of the phosphate salt to 10 to 35 veight percent of partially amidated polyalkyleneimine. An agueous solution of the components is applied to the fiber in an amount sufficient so that at least about 0.2%. and preferahly at least. 0«4% of the active component coating is deposited, based on the veight of fiber. Amounts of up to 0.9% of the mixture can be used, hovever the minimum effective amount vill normaily be employed because of cost and because fouling of eguipment is more likely to occur vith use of excessive amounts. It is important that the fiber be dried shortly after application of the antistatic finish since diminished protection is noted vhere the fiber is alloved to dry under ambient conditions. 2 LV 11047
It is particularly preferred to apply the active components to the fiber as a mixture. When using the partially amidated polyethyleneimine in combination with potassium n-hexyl phosphate or potassium n-octyl phosphate, one obtains a clear aqueous solution at concentrations of up to 15% or more (combined weight of the two active components).
The folloving examples, except for the Controls, are illustrative of the invention and are not intended as limiting. EXAMPLE-1
To a clean glass mixing vessel were added in order 80.18 parts by veight of demineralized water, 16.07 parts by veight of 70% potaseium n-octyl phosphate solution, and 3.75 parts by veight of partially amidated polyethyleneimine made according to Examples 1-4 of U.S.Patent No. 3,597,265 (amine valueof 340-420). The mixture vas varmed to 35-40*C and agitated for about 15 minūtes until a clear 15% solution resulted. The solution pH vas 10.23. EXAMPLE 2 - Control
To a clean mixing vessel vere added, in order, 85 parts by veight of demineralized vater and 15 parts by veight of the partially amidated polyethyleneimine of Example 1. After mixing for about 15 minūtes, a clear solution resulted. The solution vas then diluted to 0.25% concentration vith demineralized vater ... EXAMPLE 3 - Control
To a clean mixing vessel vere added in order 80 parts by veight of demineralized vater and 20 parts by veight of 75% potassium lauryl phosphate solution. The mixture vas agitated for about 15 minūtes until a uniform, milky, opaque 15% emulsion resulted. Aliquots of this emulsion vere diluted to 0.75% and 1.0% concentrations vith demineralized vater. 3 EXAMPLE 4 - Control
To a clean mixing vessel were added in order 78.6 parts by veight of demineralized water and 21.4 parts by 5 veight of 70% potassium n-octyl phosphate solution. The mixture was agitated for about 15 minūtes until a uniform, milky, opague 15% dispersion resulted. Aliguots of this dispersion were then diluted to 0.75% and 1.0% concentrations with demineralized vater. 10 EXAMPLE 5 - Control
To a clean mixing vessel vere added in order 66.7 parts by veight of demineralized vater and 33.3 parts by veight of 45% potassium hexyl phosphate solution. The 15 mixture vas agitated for about 15 minūtes until a clear solution resulted. Aliquots of this solution vere then diluted to 0.75% and 1.0% concentrations vith demineralized vater. 20 EKMPLE 6
Finish solution as made in Example 1 vas diluted to 1% concentration vith demineralized vater, and 5 grams of this solution vas added to a beaker containing 5 grams of 1.5 denier, 1 1/2 inch, aramid staple (Type E-34 25 Nomex0) made according to U.S. Patent No. 4,668,234. The staple and finish solution vere kneaded vith a glass stirring rod for about 5 minūtes to distribute the finish solution uniformly on the fibers, and the staple fiber dried immediately after the kneading step usinga dryer at 30 a temperatūre of 130*C and a drying time of 10 minūtes.

This staple vas then placed in a beaker, 5 grams of 0.75% finish emulsion from Example 3 vas added, the staple vas kneaded for 5 minūtes and dried for 10 minūtes at 130 1C. EXftMPLE..ll

Staple samples prepared in Examples 6-14 were converted to short lengths of sliver using a RotorRing Modei 580 manufactured by Spinlab. The electrical 10 resistivity of the sliver samples vere determined using the method described for sliver in the literature (Thomas J. Proffitt, Jr., "Surfactantsas Textile Antistatic Aģents", in Proceedinos of Session Lectures and Scientific Presentations on ISF-JOCS World Concrress. Vol. II. p. 699, 15 The Japan Oil Chemists' Society, ToJcyo). Results are in Table 2 for resistivities expressed as their logarithms, Log r. Log r values vere measured at 47% relative humidity and repeat measurements vere made as sliver vas aged. According to S. P. Hersch (DECHEMA Monoor. 72:199 20 (1974)) Log R values of 10 or less indicate excellent stātie protection. 25 30 35

Samples were made with three finish flow rātes for each of the tow products. The tow samples were then placed in tov cans and moved immediately (-20 minūtes lag time) to a drum dryer vrhere they vere dried at 110-140*C. The tow samples vere then cut to 1 1/2 inch staple using a Lummus cutter. Staple vas processed on a chute-fed, roller-takeoff, cotton-system card vith acceptable electrostatic charging vhen finish Ievel vas 0.2% on-veight-of-fiber or higher, and fiber cohesion vas improved. Finish Ievel changed very little vith age as shovn in Table 3, and electrostatic charging and Log R change very little vith age as shovn in Table 4. Cohesion as measured by card sliver tenacity in nilligrams/denier ranged from 2.46 to 3.84 for fiber vith the finish from Example l versus 1.43 to 1.83 for fiber vith a control finish, potassium lauryl phosphate.
